I continue to have this same issue repeatedly across many different decks received from clients and used at huge live events. It has become extraordinarily problematic and embarrassing.
Still continues even after trying "Insider Current Channel (Preview) Version 2401.
This is happening on a few different Microsoft Surface Books, all of which are as up to date as possible for OS, Firmware, PPT, etc., as of 1-24-24.
There is a few second lag before notes appear and then if you move BACKWARD on the deck, the notes (from the prior slide that was slow to appear) do not clear out to reflect the other slide's notes.
